| 摘 要： | 本文推导了考虑初始弛度的输电线的非线性振动偏微分方程 ,并采用伽辽金过程而得到常微分方程。应用多尺度法和L -P(Lindstedt_poincare)法求得了受谐扰力和脉冲激励的输电线非线性振动响应的近似解。分析了初始弛度对响应的影响 ,得到了一些有益的结果。这些结果对于架设电线或维护输电线安全 ,都将是有益的参考。

| Abstract: | In the paper,the partial differential equation of nonlinear vibration of a suspended power line in consideration of initial relaxation degree is derived and an ordinary differential equation is obtained by using the Galerkin procedure.The approximate solutions of nonlinear vibration responses of a power line under harmonic forces and pulse excitations are found with the help of multi-scale method and Lindstedt-poincare method.The influence of initial relaxation degree on responses is analyzed and some useful results are obtained which are beneficial references for putting up overhead power line and maintaining the safety of power transmission lines. |
